1.8m Vehicle-Mount / DriveAway Mobile VSAT

1.8m Vehicle-Mount / DriveAway Mobile VSAT Overview

AvL’s Model 1878 Vehicle-Mount / DriveAway Mobile VSAT antenna features an offset 1.8m reflector and the patent-pending AvL Cable Drive positioner for reliability and ease of operation. The Model 1878K mobile broadband antenna system is a motorized, palletized antenna with a Fixed Ku-Band Precision feed or a Fixed C-Band feed. The Model 1878 provides connectivity in remote environments worldwide where larger aperture antennas are desired to combat rain-fade and weaker satellite signals.

Created for use where performance really matters, AvL’s Vehicle-Mounted / DriveAway Mobile Broadband systems enable video, voice, IP and data communication anywhere in the world, with the push of a single button. The precision of AvL’s patent-pending AvL Cable Drive positioners paired with the ease of one-button Auto-Acquisition and superior technical support make our vehicle mount antennas ideal for non-technical antenna operators.
